One tip I learn: for Sec 1 Math, actually the foundational stuff matters most. If your child didn’t master things like fractions, decimals and area perimeter properly in primary school, they will really struggle when Sec 1 starts ramping up. Maybe consider doing some diagnostic assessment first to identify the weak spots before spending money on a full tuition programme. Btw I also tried OmniBox Tutor for my boy — quite handy for quick homework help when I can’t figure out his questions myself. Anyway good luck with the search!
